10BT/100TX PCI LAN
Connector
Ultra wide (16-bit) SCSI
connector
The LAN adapter supports the following two standards: 100 VG-AnyLAN,
100 Mbits per second over 4-pair, category-3, unshielded twisted pair
(UTP), voice grade (VG) cable (IEEE 802.12 standard for Ethernet);
10 BaseT, 10 Mbits per second, ISO 8802-3 (IEEE 802.3 standard). On the
rear panel there is one RJ-45 unshielded-twisted-pair (UTP) connector. The

SCSI Interface
The Symbios Logic SYM5C875J PCI-SCSI I/O Processor chip connects
directly the SCSI bus and generates timing and protocol in compliance with
the SCSI standard.
The SCSI interface operates as 16-bit, synchronous or asynchronous, single-
ended, and supports Ultra SCSI protocols and 16-bit arbitration. The
interface is made through two (and only two) of the connectors J2, J3 and
J4.
Connector
J2
Shielded 68-pin high density right-angle receptacle.
J3
68-pin high density right-angle receptacle.
J4
External Start, SCSI Led and External SCSI cable
detection.
The Ultra wide 16-bit SCSI connector is for internal devices and has an
address range from 0 to 15, with the SCSI address 0 used by the first SCSI
hard disk drive and SCSI address 7 reserved for the integrated SCSI
controller (the default for wide and narrow SCSI devices).
Data is transferred at 40 MB per second on 16-bit wide, single-ended bus.
The controller is fitted with a 16-bit SCSI flat cable with five connectors,
plus a SCSI termination device; so a maximum of 4 internal wide-SCSI hard
drives are supported.
